FWIW, talking to a buddy that was ATL 767 B on reserve living in base, he bid off and started commuting after he was being used "every day" but coming up with 69 hours of credit. So I think thats not every day but the point is it was a lot of work that he found 73N NYC commuting a better deal.
I like 88 ATL reserve, the money hurts, but the lifestyle has been good for me.
